Natural Bridge Caverns
Filter by Subject
Vernier recently attended the GLOBE annual conference in San Antonio, TX, where we sponsored a field trip to Natural Bridge Caverns, a limestone cave. Sixty teachers made their way through the wet, drippy tour of the caverns and collected relative humidity, temperature, and barometric pressure data along the way.
Due to the recent, heavy rains in the region, the water in the cavern rose high enough to measure the pH of the water in the aquifer. Five Vernier sensors meet GLOBE Program specifications: Relative Humidity Sensor, Stainless Steel Temperature Probe, pH Sensor, Conductivity Sensor, and Dissolved Oxygen Sensor.
